Rock Crushing Theory and Formula using Kick Rittinger’s Law
2016年3月11日 Rittinger’s theory and law of the energy expended in crushing of rock is that the work of crushing is proportional to the reduction in diameter; or, as I have more fully expressed it: “The work done in crushing is proportional to the surface exposed by the operation; or, better expressed for this purpose, the work done on a given mass of rock is proportional to the 2019年9月21日 9 Cutting (Shear) (Mechanisms of Size Reduction) Shear/cutting consists of a trimming or cleaving (chop, slice, cut etc) action rather than the rubbing action associated with attrition Cutting gives a definite particle size and some time a definite shape, with few or no fines Shear is usually combined with other methods For example, singleroll crushers employ shear 3 size reduction PPT SlideSharetechnologies also require lab measurements to track changes in particle size including crushing, homogenization, emulsifi cation, micro fl uidization, and others Separation steps such as screening, fi ltering, cyclones, etc may be monitored by measuring particle size before and after the process Particle size growth may beA GUIDEBOOK TO PARTICLE SIZE ANALYSIS Horibathe particle size distribution functions of a mill product Figure 112 provides the particle size distribution of a mixture of two plastic waste products After grinding, the particle size distribution changed to that shown in Figure 113 Clearly, the two different types of plastic displayed different behaviour during crushing Both were crushed:11 Crushing and classification
